T 0 all whom it may concern:

Be it known that I, NATHAN Sonznnncnn, a citizen of the United States of America, residing at No. 34 West Seventh-first street, New York city, in the county of New York and State of New York, have invented new 1, anduseful Improvements in Making N on}; Odorous Phenol Salves and Ointments, of which the following is a specification.

The well established valuable antiseptic and anal esic qualities of the phenols (carbolic acid, cresols, etc. and derivatives of same) and their mixtures are offset detrimentally to their more general use by their objectionable and very penetratin odor, which oftentimes clings to the skin even after the salve has-been removed and washed off. This objection reveals itself most par ticularly when the 'phenolsare used in form of salvesand .ointments since in this articular form the phenols are mostly use externally on sores and wounds of the skin.

It has now been found that salves and I ointments, etc. still possessing the antiseptic and analgesic action of the henols can be prepared to take the place 0? all such ointments, etc. heretofore manufactured with the strong smelling phenol compounds themselves by their odorless higher fatty acid esters, such as for instance, the phenol esters of palmitic and stearic acids (and their mixtures).

Phenyl-stearate can be obtained by heatmg together five hundred gr. of dried stearic acid with 100 gr. phosphorus trichlorid for several hours at from 80 to 90 degrees C. The stearic acid chlorid, freed from the excess of the phosphorus trichlorid and from phosphoric acid is then brought into reaction with about 200 gr. phenol and after the "spontaneous evolution of hydrochloric acid hasceased, is heated for 3 to 4 hrs. to 85 to 90 degrees C. The product carefully washed and dried is ready for use. Phenyl oleate can be prepared in similar mannerzIn one case 600 gr. of dried oleic acid were heated together'for 5.130 6 hrs. with 110 gr. phoshorus trichlorid in a flask with reflux conenser, The chlorid freed from the excess of phosphorus trichlorid and from the formed phosphoric acid was brou ht into reaction with 220 phenol and a er the evolution of 'hydroc loric acid had ceased at ordnary temperature, the temperature was gradually raised to about 85 to 95 degrees C. and kept Specification of Letters Patent. Application filed April 7, 1909. Serial no. 488425.

Into such salves and oint ments can also be mixed a great number of chemicals of phermaceutical'value, if so de slred, since these fatty acid esters do not interfere with the action of a great many of these bodies. For example, to obtain a 53 of proper consistency containing henylstearate' I can melt together about equal parts of phenylstearate and liquidpetrola tum (or benzoinated lard or lanolin or white Vaseline). To obtain a salve containing some chemical substance besides, I cite'for instance the following formula for aborax slave; 40 parts phenylstearate 30 parts liquid petrolatum, 10 parts white 'wax' and '20 parts of an a ueous saturated solution of borax. These saves are all white bodies unless colored through the addition of foreign matter. They may be perfumed wherever desired. Ssilvesv can also be made by mixin liquid phenol oleates with the solid fatty acid esters. These latter need contain 'no foreign fat or oil at all and therefore consist of much greater percentages of phenol. In making a salve with the liquid phenyl oleate the following formula can be used: 40 parts. phenyl oleate, 20 parts wax and. 40 parts lanolin.

Instead of using the pure fatty acid phenol esters, the phenol esters made from the crude or commercialacids (as such fatty acidsare for instance obtained by saponifyi'nganimal and vegetable fats and o ls) may be emloyed in making these salves and ointments. uch salves and ointments may also contain there for about 5 hrs. Finallythe temperi mixtures of fatty acid esters madevfrom a mixture of phenols (for instance, when such esters are made from mixtures of cresols). I claim: 7 1. A11 antiseptic salve of the'nature disclosed, composed of phenyl-stearate melting at about 52 C. and having mixed therewith some suitable unguent adapted to lower the melting-point of the phenyl-st'earate and to impart to the resultant compound a greaselike consistency.

4. A non-odorous non-irritant composite antiseptic salve of the nature disclosed for pharmaceutical and medical use, composed of an ester of a phenol and a fatty-acid havin more than twelve atoms of carbon, in mixture with a sufiicient quantity of a suitable unguent to impart to the resultant mixture a melting point of a proximately body-temperature whereby sai mixture may have a salve-like consistency enabling it to be readily smeared on the skin; said phenol being mono-hydric and having the capacity of forming with stearic acid anester melting at not less than about 40 C.
